Abstract

An air cleaner of an internal combustion engine has a housing with a slide-in opening and receives a slide-in filter element through this opening. A cover element closes off the slide-in opening. The cover element has a snap element for fixing the cover element at the housing. The cover element has a contact face defining a first main plane. A sealing is disposed between the filter element and the housing and seals between filter element and housing. A sealing face provided at the housing interacts with the sealing and defines a second main plane. The housing has a contact face abutting the contact face of the cover element in the closing state of the cover element. An angle between the second main plane of the sealing face of the housing and the first main plane of the contact face of the cover element is different from 90°.

First claim

What is claimed is:

1 . An air cleaner of an internal combustion engine, the air cleaner comprising:
a housing comprising a slide-in opening and adapted to receive a slide-in filter element through the slide-in opening; a cover element closing off the slide-in opening in a closing state of the cover element, wherein the cover element comprises at least one one-piece snap element adapted to fix the cover element at the housing, and wherein the cover element has a contact face defining a first main plane; a sealing disposed between the filter element and the housing and adapted to seal between the filter element and the housing; a sealing face provided at the housing and adapted to interact with the sealing, wherein the sealing face defines a second main plane; wherein the housing has a contact face abutting the contact face of the cover element in the closing state of the cover element; wherein a first angle between the second main plane of the sealing face of the housing and the first main plane of the contact face of the cover element is different from 90°.

2 . The air cleaner according to claim 1 , wherein a tension force of the at least one snap element generates a first force component and a second force component, wherein the first force component is perpendicular to the first main plane of the contact face of the cover element and wherein the second force component is perpendicular to the second main plane of the sealing face of the housing.

3 . The air cleaner according to claim 2 , wherein a second angle between a direction of the tension force of the at least one snap element and the first main plane of the contact face of the cover element is different from 90°.

4 . The air cleaner according to claim 3 , wherein the second angle is between 20° and 70°.

5 . The air cleaner according to claim 4 , wherein the second angle is approximately 45°.

6 . The air cleaner according to claim 3 , wherein a third angle between the direction of the tension force of the at least one snap element and the second main plane of the sealing face of the housing is approximately 90°.

7 . The air cleaner according to claim 1 , further comprising a sealing element arranged between the contact face of the housing and the cover element.

8 . The air cleaner according to claim 1 , wherein the slide-in opening is arranged on a raw-gas side of the filter element.

9 . The air cleaner according to claim 1 , further comprising a drawer, wherein the cover element forms a part of the drawer, wherein the slide-in filter element is positioned in the drawer and the drawer is adapted to slide through the slide-in opening into the housing.

10 . The air cleaner according to claim 1 , comprising at least one snap face arranged on the housing, wherein the at least one snap face is adapted to interact as a counterpart with the at least one snap element so as to fix the cover element at the housing.

11 . The air cleaner according to claim 10 , further comprising at least one counter support, wherein the cover element has an end opposite the at least one snap face and the at least one snap element, wherein the at least one counter support is adapted to connect said end of the cover element to the housing.

12 . A filter element comprising a pleated filter medium and a circumferential elastic sealing, wherein the filter element is adapted to be inserted into a drawer of an air cleaner according to claim 1 .
